GN 749 Threaded Pipe Plugs Steel, zinc plated, with NBR Synthetic Rubber Seal


Product description


GN 749 threaded pipe plugs seal is retained in a groove undercut in the mating face, which prevents it from dropping out and from extruding when the plug is tightened. For this reason the seal can be of a softer material which offers better sealing.

The details relating to the permissible operating pressure are non-binding recommended values and rule out any liability. They constitute no general warranty of quality and condition. The user must determine from case to case whether a product is suitable for the intended use.
